PAT NT JAMES W'INTERTON, OF BIRMINGHAM, ENGLAND, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, TO JAMES GEORGE ACOLES, OF SAME PLACE.

PLATEN PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 513,357, dated January 23,1894.

Application filed July 28,1892. Serial No. 441,529. (No model.) Patented in England January 19, 1891, N0. 913.

To all whom it may concern.-

Be it known that 1, JAMES WINrERToN, mechanic, a subject of the Queen of Great Britain, and a resident of Perry Barr, Birmingham, England, have invented certain new and useful Improvements in Platen Printing-Machines, (for which Ihave obtained a patent in Great Britain, No. 913,bearing date January 19, 1891,) of which the following is a specification, reference being had to the accompanying drawings.

Myinvention relates to platen printing machines having two, three or more platens. On machines of this class as heretofore constructed a perfect register cannot be obtained without carefully handling and adjusting the paper every time a different color is to be printed thereon.

According to my invention I combine in one machine two or more sets of apparatus each set comprising a type bed, ink-distributing apparatus, throwing oif gear and other usual accessories. Each type-bed, in addition to the usual parts, is fitted with means for adjusting the form so that it will give a perfect register with an impression taken from the other or one of the other type-beds; there are also means for regulating the strength of the impression.

Improved means are provided for moving the platens successively into position in front of the different type-beds and for locking the said platens and holding them securely and rigidly while the impression is being taken from the form on each type-bed and then releasing them to permit them to be moved onward to the next type-bed.

My said invention also includes improved means for giving the inking rollers a lateral movement as they travel over the type, so that it shall be well rolled.

My improved machine is so constructed that either or any one of the type-beds may be used alone with either or any of the platens, or with all the platens in rotation, or the whole of the platens and type-beds may be in use at the same time. By these means I am enabled to print in perfect register on one sheet as many different colors as there are type-beds.

I11 order that my said invention may be clearly understood I will now proceed to describe the same with reference to the accompanying drawings, in which Figure 1 is a side elevation of a machine provided with a series of rotative platens, and two type-beds and their accessories. .Fig. 2 is an end elevation of the machine illustrated in Fig. 1. Fig. 3 is a transverse vertical section of Fig. 1, through the platens. Fig. 4 is a plan of Fig. 3. Fig. 5 is an elevation of part of the frame of a machine and illustrates a device for locking the platens which is supplementary to the device employed for a like purpose in Figs. 1 and 2. Fig. 6 is a plan of Fig. 5. Fig. 7 is an elevation of a type bed and of the frame which supports the same and shows the means whereby the type-bed is adjusted on the frame, and the form on the type-bed. This figure also shows improved means for imparting a lateral movement to the inking rollers to insure better rolling. Fig. 8 is a vertical section on the line 2 z of Fig. 7. Fig. 9 is an elevation of the runner or disk which is fixed on the end of the inking roller for a purpose hereinafter fully explained. Fig. 10 is an elevation of the said runner or disk at right angles to Fig. 9, and Fig. 11 is a vertical sectional view taken on the line 11-11, Fi 2.

iike letters indicate corresponding parts throughout the drawings.

a is a frame of suitable construction for carrying the parts of the machine. 1) is the crank or driving shaft which issuppor'ted in bearings in the said frame.

c c are the platens and o is a block to which the said platens are secured and on which they are adjustable by means of screws 0 I prefer to provide each platen with four of these screws. The said platens are provided with blanket-irons and grippers in the usual manner. By making the platens separately and mounting them adj ustably on the block, I provide for very readily adapting the surfaces of the platens to that of the forms on the type beds.

at is a shaft which carries the platens in such a manner that they can turn independently about the said shaft. On one end of the shaft d is fixed a wheel or disk e and on the other end is a gear wheel e driven by a pinion f on the driving shaft 1).

g g are the type-beds which are carried by oscillating frames 9 mounted on shafts g extending across the framing. The type bed frames are oscillated about their shafts by the gear wheel 6 and the disk e, through the medium of connecting rods h.

2' t' are the ink ducts or fountains.

jj are the inking rollers.

l0, k are the roller carriers or arms pivoted to the type bed frames at k and provided with springs in the usual manner for keeping the inking rollers properly in contact with the type. The platens as above specified rotate around the shaft d. They are moved successively from one type-bed to another to take the different colors. For this purpose I employ in'the present instance a hooked rod Z which is connected to one of the connecting rods h at Z. The hook Z at the free end of the rod is formed and arranged to engage with pins or studs 0 on the platen block a.

For locking the platens while the impression is being taken from either of the type beds I hinge to the frame of the machine, opposite each end of the platen block arms at connected together by a bar m and hinged to the frame at m the said arms being arranged to enter grooves c which extend across the ends of the platen-block c. Springs 12 secured to the frame bear against the arms m so that the arms will be caused to engage with the platen block as soon as the grooves 0 come opposite the said arms. On each bar 'mand midway between the two arms is an anti-friction roller m and upon the shaft 01 is a segmental cam 0, the leading and following ends of which are beveled as shown. In the present example, there are two sets of parallel grooves c on each end of the platen block c, the said sets being arranged at right angles with each other, so that in every ninety degrees of rotation of the said platen block, that is to say, as each platen arrives in front of a type-bed, a pair of the grooves 0 will come opposite to the ends of the twin arms m. To the roller carriers k at k I connect links p which are also jointed or pivoted at p to the frame of the machine. The said links hold the arms 7i; so that in the movements of the type-bed the said roller carriers are caused the type beds relatively to the framing of the machine.

In the operation of the said improved machine the driving shaft is rotated by means of the treadle b in the usual manner, or by any convenient power, and. rotates the pinion f, which by means of the gear wheel 6' rotates the shaft d. The-disk e and gear wheel 6 on the ends of the said shaft vibrate the two type-bed frames g about their shafts g by means of the connecting rods It so as to bring the two type-beds g alternately toward the platens on the platen-blocks c. As the shaft 01 rotates, the cams 0 thereon engage wlth the anti-friction rollers m and pass between the bars m and the ends of the platen-block so 4 as to force the arms mout of the grooves 0 against the resistance of the springs n, and as the connecting-rod to which the hooked rod Z is attached, recedes from the platen block, the hook at the end of the rod engageswith one of the pins c upon the platen block and turns the said block through an angle of ninety degrees. Before the platen-block completes this angular movement the cams 0 will have passed clear of the anti-friction rollers on the bars m and the arms 472 will bear upon the end of the platen block and Will be forced by the springs n into engagement with another set of the grooves 0 as soon as the ninety degrees of angular movement is completed. In the return movement of the connecting-rod with the hooked rod Z the said rod will ride over the pin with which it has ust previously been engaged and will engage with the pin next in order upon the platen-block and assume a position in readiness to give the said platen-block another quarter of a revolution and so on. Thus the platen-block receives intermittent movement which takes place while one type bed recedes from the platen-block and the other one approaches it.

With reference now to Figs. 10 and 1l projections s of suitable form are provided on the inside of the disk 6 and of the gear wheel e and a stud or bolt 5' is fixed upon each pair of locking arms m as shown. The said projections are suitably situated on the disk and the gear wheel so that at the proper times they will engage with the studs 8' and keep the arms m in engagement with the platen block to lock the same at the moment ofimpression. This is an additional or supplementary arrangement adapted for use with the lockingapparatus hereinbefore explained.

I will now proceed to describe Figs 7, 8, 9, and 10. To provide for accurate register in the use of thev series of type beds I fit the same with screws 16 at the sides so arranged that the will bear upon the form, which may be adjusted laterally on the bed and securely held in any position to which it may be adjusted by turning the screws so as to move them in or out. Moreover for making ready or regulating the strength of the impression I provide one or more of the type beds with IlO 1o printed sheet.

513,357 I v t 3 said plate and passes through the back of the type-bed which is made up of deep'ribs 5 v are nuts upon the said screws by means of which the said false bottom 9 which carries the form can be adjusted to raise or depress any part of the form so as to insure the 'uniform action of the same upon the On the ends of the inking rollers runners to, Figs. 9 and 10, are secured each runner having a flange or project ing rim w, and, in a ribbed flange at the edges of each rocking frame g grooves g are :5 formed. There are two grooves g as shown on eachsaid flange and each groove is straight for the greater portion of its length and has at its end a curved or laterally inclined portion by which it is connected with the adjacent groove as shown; the rim to of the runner travels in the said grooves, the straight portions of which are made a li'ttledeeper than the inclined portion, so that the runner, moving in each groove in the direction of the 2 5. arrow placed therein, iscaused to drop from the inclined portion of one groove into the straight portion of the other in order that it may travel in each of the grooves in turn. The lateral movement of the runner as described from one groove to the other imparts 3 5 cessful printing.

What I claim is 1. In a printing machine, the combination with the framing thereof, of a rotative platen-. block having a grooved end, arms hinged to r40 the said framing, springs carried by the said framing and bearing upon the said arms, antifriction rollers carried by the said arms, a shaft supporting the rotative platen-block, and cams caried by the said shaft and adapted to engage with the said anti-friction rollers,

substantially as set forth. 4

2. In a printing machine, the combination of a rotative block, platens carried by the said block, a shaft supporting the said block, a wheel and disk secured on the shaft, grooves in the ends of the said block, arms hinged to the framing of the machine and adapted to enter the said grooves to keep the said block stationary, a cross-bar connecting the arms of each pair of arms and bearing a stud, and projections carried by the aforesaid wheel and disk secured on the shaft by which the platenblock is supported, said projections operating to engage with the studs and keep the said arms in engagement with the said grooves, all substantially as and for the purposes set forth.

3. In aprinting machine, the combination with each inking roller, of a runner provided with a flange or rim, and of ribs upon the flanges of the type-frame, the body of the frame being so formed that the ribs have spaces between them constituting grooves, the latter having parallel straight portions and laterally inclined portions, the inclined portions being of less depth than the straight portions, substantially as set forth for the purpose specified.

4. The combination with a series .of rotative platens carried upon a block which is adapted to turn about a shaft supported by the framing of the machine, of two or more type-beds carried upon oscillating frames, a I

disksecured to a shaft which is rotated by means of a treadle or otherwise, connecting rods connected to the said disk and to the said oscillating frames, a hooked rod attached to one of the said connecting rods, pins or projections upon the platen-carrying block, rollercarrying devices hinged to each oscillating frame, and links hinged to the said roller-carrying devices and to the framing of the machine, all substantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
